Novinit, a French company, has developed the world's first TDA or Tactile Digital Assistant. The TDA is based on touch-screen technology and relies entirely on your thumbs for input, which are harder to lose than a stylus. The TDA is named Jackito and comes with two simultaneous touch points so you can operate it with your thumbs at the same time and so no need for a stylus. Using the TDA is very easy, since you can search a database or a large address book, with just your thumbs. Using the device with your thumbs is actually much faster than a stylus (well at least that's what the company claims).
